Facts: 

The oil extracted from Calophyllum inophyllum seeds has been explored as a potential source of biodiesel. The tree’s high oil content and ability to grow in marginal lands make it an interesting candidate for sustainable biofuel production.

Pounded seeds are applied on the abdomen for gastric pains, indigestion and colic in the Philippines. Seed oil is used as a cicatrisant and as balsamic (soothing medicine) in pulmonary complaints.

Besides traditional medicine, this tree has been studied for its potential pharmacological properties. Some research suggests it may have anti-inflammatory, antioxidant, and antimicrobial effects, supporting its traditional use in treating various skin conditions.

Calophyllum inophyllum is planted as a roadside tree, shade tree, in hedges and as a wind break, and landscape ornamental plant in parks, gardens and coastal areas.
